WRENCH.

SPECIFICATIQN foriningpart of Letters Patent No. 697,241, dated April 8, 1902.

Application filed January 14, 1902. Serial No. 89,723. (No model.)

To all whom, it may concern:

Be it known that I, FULTON V. EURIOH, a citizen of the United States of America, residing at Tarentum, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Wrenches, of which the followingis aspecification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in wrenches, and relates more particularly to monkey-wrenches having sliding jaws.

The present invention has for its object the provision of novel means to permit an easy and rapid adjustment and movement of the sliding jaws; furthermore, to provide novel means to securely lock and retain the jaw in a firm position after it has been adjusted to the desired point.

The invention further aims toprovide a wrench that will be extremely simple in its construction, strong, durable, comparatively inexpensive to manufacture, and highly efficient in its use.

Vith the above and other objects in view the invention consists in the novel combination and arrangement of parts to be hereinafter more fully described, and specically pointed out in the claim.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this speciicatiomand wherein like numerals of reference indicate like parts throughout the several views,in which- Figure 1 is a plan view of my improved wrench. Fig. 2 is a similar view showing the sliding jaw in vertical section.

My improved wrench comprises in its construction a handle 1, which has an integral jaw 2, and on its inner face is provided with teeth 2u. Mounted to slide on the handle 1 is a jaw 3, comprising acasing through which the handle 1 extends, this casing having a cutaway portion 4., forming an arm 5, and in this cut-away portion 4 the worm 9 is adapted to operate. This worm 9 is mounted on an operating-shaft 8, the inner end of which is pivoted, as at 7, within arecess 6, formed therefor in the jaw 5. This recess 6 is of a size to permit swinging movement of the shaft 8 to disengagc the worm 9 from the teeth '2 when it is desired to move the jaw 3 any consider: able distance on the handle 1. The shaft 8 is provided on its outer end with a head 15, and the arm 5 is provided with an opening 10, through which the shaft S extends, this opening being of considerably greater diameter than the diameter of the shaft in order to permit the latter to be moved away from the handle, and thus disengage the worm 9 from the teeth 2a when desired. A locking-sleeve 11 is slidingly fitted on the shaftS and is enlarged at its outer end 12, so as to afford means whereby the sleeve may be grasped with the fingers and moved along the shaft 8 out of engagement with the arm 5. The sleeve is normally held in engagement with said arms 5 by a spring 14, arranged on the shaft 8 between the outer end of the sleeve and the head 15 of the shaft.

When the movable j aw requires buta slight adjustment, the worm-collar is operated, thereby causing the jaw to be moved a slight distance; but when it is desired to operate the sliding jaw quickly to obtain a rapid adjustment of the wrench the sleeve l1 is driven downwardly out of engagement with the opening 10 of the extension 5, thereby releasing the operating-shaft to an extent that will allow the latter a slight movement, as indicated in dotted lines in Fig. 2 of the drawings, thereby disengaging the worm-sleeve from the teeth of the handle and permitting the jaw to slide freely upon the handle of the Wrench. When the operating-shaft is released,the same will again assume its former position and the tension of the spring will force the sleeve into the opening formed in the extension, and the device will again be in a locked position, as heretofore stated.

The many advantages obtained by the use of my improved device will be readily apparent from the foregoing description, taken in connection with the accompanying drawings.

It will be noted that various changes may be made in the details of construction without departing from the generalspirit of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination with a handle having a toothed face and an integral jaw at one cud,

IOO

of a sliding jaw mounted on the handle and having a cut-away portion forming an arm at one end of the jaw, a worm mounted in the cut-away portion of the jaw, an operatingshaft pivoted at its inner end to the jaw and on which the worm is rotatably mounted, said shaft extending through an-aperture provided therefor in the arm of the jaw and having a head on its outer end, a locking-sleeve mounted to slide on the shaft and engage in the aperture in the arm to retain the worm in engagement with the teeth of the handle, the said shaft being capable of swinging movement In testimony whereof I affix my signature 2o in the presence of two witnesses.
